Report: Mercedes pulls the plug on range-extended EV possibilities

Baua Electric

Mercedes built and tested some prototypes based on existing models, “concluded that the range-extender drivetrain is a transitional technology with a relatively short-term benefit in terms of sales and comparatively high production costs,” the source told Autocar. One of the prototypes was reportedly an EQS with a front-mounted 1.0-liter

Pierburg GmbH electric compressor for turbos

Green Car Congress

Pierburg GmbH, part of the KSPG Group, has developed an electric compressor for spontaneously boosting the charge pressure of engines fitted with an exhaust-gas turbocharger. This component allows pressure to be increased regardless of the exhaust-gas energy availability.

Ricardo’s “deep” Miller cycle concept: Magma

Green Car Congress

In its new report on downsized and boosted gasoline engine technologies ( earlier post ) the ICCT highlighted Ricardo’s work on an “extreme” Miller cycle concept with high (13:1) compression ratio (CR) and central direct injection in a downsized boosted engine. A long exhaust stroke then extracts maximum efficiency. Resources.

PSA to commercialize SwRI-developed Dedicated-EGR technology in high-efficiency gasoline engines by 2018

Green Car Congress

The D-EGR concept dedicates one (or more) cylinders to EGR production and fuel reforming. D-EGR, as proposed and developed by SwRI, envisions engines with individual cylinders dedicated to EGR production to overcome the challenges associated with EGR tolerance and control.
